When simple-audio-card programs sysclk for CPU and codec DAIs during hw_params, the ordering of these calls may matter on some platforms. Some CPU DAIs finalize or adjust the MCLK rate as part of their set_sysclk() callback (for example by calling clk_set_rate()). If the codec sysclk is configured before the CPU DAI applies the final MCLK rate, the codec may configure its internal clocking based on a non-final MCLK value. Such situations can arise depending on the clock provider/consumer relationship between the CPU DAI and the codec. Introduce an explicit sysclk ordering enum in simple-card-utils and use it to control the order of snd_soc_dai_set_sysclk() calls in the mclk-fs handling path. The default behaviour remains unchanged (codec-first) to avoid regressions.
